title: [Prevalence of hospital admission due to adverse drug reaction in Salvador, Bahia].
abstract: OBJECTIVE
  To determine the prevalence of hospital admissions due to ADR in Salvador, Bahia and their outcomes.
  
  
  METHODS
  All patients admitted in four Sentinel Hospital (ANVISA) in Salvador-Ba were evaluated and followed to determine the prevalence of admissions due to ADR and their outcomes from April to December 2007. Cases were validated by 03 algorithms. The drugs were classified by Anatomical-Therapeutic-Chemical Classification, organs and systems affected by the WHO criteria and severity seconds Pearson et al. Type of ADR was analyzed by Rawlins and Thompson.
  
  
  RESULTS
  The prevalence of ADR admission was 0.5% and adjusted for exposed was 2.1%, with 316 cases. Average of hospitalization due to ADR was 12.3 days. Younger and older accounted for 28.8% and 31.1% of patients. Females and blacks were 60% of cases. Main pharmacologic groups were antineoplastics, antibiotics and diuretics, affecting skin, gastrointestinal and hematologic systems. Around 70% of the ADR was validated as defined. ADR of type A was 80% and 90% recovered, and one death (0.5%).
  
  
  CONCLUSIONS
  The prevalence of ADR admission was similar to those described in the literature and only one patient died. As this is the first national study will form the basis for future investigations.
